Description

Technical Field

[0001] This invention pertains to food processing equipment, specifically a compact and lightweight device for rapidly and easily chopping ready-to-eat foods, applicable to the food industry. Background Technology

[0002] Eating is a fundamental human activity, requiring healthy teeth to chew food. However, due to factors such as poor hygiene, food obstructions, and varying health conditions, teeth can become damaged or lose function, leading to difficulty chewing food and causing eating difficulties. To address this, mechatronics and automatic control technologies can be used to create lightweight devices that replace the chewing function of teeth, chewing small, bite-sized portions of food for easier eating.

[0003] Therefore, a suitable loading container is required. Once food is placed inside, its presence should be detected, and processing should begin. The processed food is then transferred to an output container for consumption. Heating and condiment addition functions can be added if necessary.

[0004] Therefore, an invention of an automatic food chewing device was proposed. Summary of the Invention

[0005] The invented automatic food chewer consists of a shell, a food inlet and channel, a food detection sensor, a rotating chewing unit, a rotating food conveying and agitating unit, a rotating transmission unit, a seasoning adding unit, a chewing drive unit, an electrical control unit, a heating unit, and a processed food container. The shell mainly comprises the outer shell and load-bearing structure of the overall mechanism. The food inlet and channel are located on the top of the shell and are used to add food to be processed. The food detection sensor is located on the food inlet and channel to detect whether food is entering and is electrically connected to the electrical control unit to transmit the seasoning. The sensor signal is transmitted to the electronic control unit; the rotating chewing unit is located at the lower part of the food inlet and channel, used to chop the food to be processed, and consists of a rotating outer cylinder and a fixed inner blade. The rotating outer cylinder is driven by the three-stage upper transmission gear of the rotating transmission unit; the rotating food conveying and agitating unit is located at the bottom of the food inlet and channel, at a certain distance from the rotating chewing unit, and has a larger diameter than the rotating chewing unit. It has blade-like protrusions on top, used to convey the falling chopped food to the processed food container and to agitate the seasoning in the seasoning addition unit using the blade-like protrusions; the rotating transmission unit is located at... Between the rotating feeding unit and the chewing drive unit, and to the side of the rotating chewing unit, there is a three-stage gear system. The third-stage gear consists of three upper drive gears and three lower drive gears. The shaft of the first-stage gear is coaxial with the chewing drive unit and is therefore driven to rotate by the chewing drive unit. The first-stage gear drives the second-stage gear through gear meshing, and the second-stage gear drives the third-stage gear through gear meshing. The seasoning addition unit is a unit with an opening at the top and a groove at the bottom, used to hold the seasonings, which are then pushed into the rotating feeding and chewing unit by the rotating feeding and chewing unit. The crushing drive unit is located below the first stage of the rotary transmission unit, coaxial with the first stage of the rotary transmission unit, and connected to the electronic control unit with electrical energy and electrical signals. It is controlled to rotate by the electronic control unit. The electronic control unit includes a microcontroller unit and an electrical energy unit, and is electrically connected to the food detection sensor, the chewing drive unit, and the heating unit. It controls the chewing drive unit and the heating unit according to the operating program. The heating unit is located at the bottom of the processed food container and operates according to the control of the electronic control unit. The processed food container is located to the side of the rotary food conveying and stirring unit and is used to hold the processed food.

[0006] The working principle of an automatic food chewer is as follows: food to be chewed is added through the food inlet and channel. The food detection sensor detects the food entering and sends a detection signal to the electronic control unit. The electronic control unit controls the chewing drive unit to rotate, which drives the first stage of the rotary transmission unit to rotate and then transmits the signal to the third stage. The third stage of the rotary transmission unit rotates, which drives the rotary chewing unit to rotate and chop the food. At the same time, the first stage of the rotary transmission unit drives the rotary food conveying and agitating unit to rotate, which causes the seasoning from the agitating seasoning adding unit to fall and conveys the chopped food to the processed food container. The electronic control unit also controls the heating unit to keep the food in the processed food container at a suitable temperature. The food is then taken out of the processed food container for consumption.

[0007] The advantages of automatic food mortars and pestles are that they provide a complete and convenient food processing method, and their fully automatic electronic control lays the foundation for a more intelligent and convenient food processing method. Attached Figure Description
